Cannot Build Project with 4.12 Preview 5

Where can I find the log? I’ve looked under AppData/Local/UnrealEngine4.12 but no log files were found.

Hey -

Can you explain exactly what the problem is you’re getting along with details about what you were doing when it occurred? Was this error encountered when compiling code or attempting to package a project? If you’re looking for the project’s log files, you can find them in the Saved/Logs folder in the project directory.

Hi ,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.

Thank you.

, after successfully converting my project from 11.2 to 12.0, some items in the scene are not positioned correctly, and they do not render at all. They are not visible in the scene even though they are in the World tree, can be clicked and zoomed on.

Since this post was for the issue of being able to upgrade / compile the project, it would be best to create a new post for the issues you’re having after the conversion. This will help prevent information from one issue being buried inside another post and will help others when searching for information regarding the same problems.
